Flex is database independant. There is no data classes with Flex, unless you are working with AIR. With Flex you connection to your data using either ColdFusion RemoteObjects or Web Services with any (CF, PHP, .NET, etc) so it is more based on what each language can use (which is all of them) and your confort with programming with each. I am a CF developer and I use CFCs to manage my data with my Flex application.
Deciding on a database is should be more based on the size of your project and your confort level with each. MySQL, MSSQL, and Oracle can all handle high transactions and heavy loads for most small, medium, and large web application. Access is never a great choice due to limited connections and file size. Access is cute, but not a good choice for an application that is going to grow. ---------------------------------------- From: "christophe_jacquelin" <[email protected]> Sent: Friday, February 20, 2009 5:07 AM To: [email protected] Subject: [flexcoders] Best database for Flex Hello, What is the best database for Flex: mySql or SQLServer ?
